Starch accumulation in S. polyrrhiza 7498 plants after MH treatment. Starch content was calculated based on fresh weight (a); or each flask (b). Plants cultivated on the medium without (c and e) or with 75 µg/mL MH (d and f) were collected on the 8th day of the experiment and stained with I2-KI (c and d) or subjected to starch granule observation (e and f) with TEM. C, V and S represents chloroplast, vacuole and starch granule, respectively. * indicates statistically significance on the level of P < 0.05; and ** indicates statistically significance on the level of P < 0.01. Each point in A and B represents mean ± SE of 3 biological replicates
